I am running 11.2.0.4 database on RedHat Linux and my scheduled jobs are on OEM Cloud Control 12.1.0.3 owned by SYSMAN. The jobs have been consistent in performance but as of last week, three of the many jobs didn't run. When investigated, the scheduled jobs are not showing on Cloud Control I tried to recreate it, thinking someone may have deleted it in error but I got the message "A job with the specified name already exists Please provide a different name". When I query the MGMT_VIEW.MGMT$JOBS, I can see that the jobs exist.
1) Where are the jobs
2) How do I locate them on Cloud Control
3) How do I get the jobs to run at the scheduled date?

The jobs have run consistently as scheduled but as of last week, three of the many jobs didn't run and are not running. When I investigated, the scheduled jobs are not showing on Cloud Control. I tried to recreate it, thinking it may have been deleted in error but I got the message "A job with the specified name already exists Please provide a different name". When I query the MGMT_VIEW.MGMT$JOBS, I can see that the jobs exist in the database.

How can I get the job to show up on Cloud Control and also how do I get it to run repeatedly as scheduled?

I am running Oracle 11.2.0.4 database on Red Hat Enterprise Linux Server release 5.10.
The jobs are on OEM Cloud Control 12.1.0.3 running as SYSMAN.
The jobs have run consistently but as of last week, some of jobs didn't run
and are not showing up on Cloud Control.
Enterprise -> Job -> Activity -> "Advanced Search"
=> Owner ( All) Status ( All) Scheduled Start (Last 7 Days) -> GO
Shows no display of the jobs that failed to run,
but there's display of the last successful run and none of the next scheduled run.

I tried to recreate the missing jobs but I got the error message:
'A job with the specified name already exists Please provide a different name'.

When I query the database, all of the jobs are displayed:
select job_owner,job_name from MGMT_VIEW.MGMT$JOBS order by 1,2;
How can I get the job to show up on Cloud Control and also how do I get it to run repeatedly as scheduled?
